Abstract (en)
[origin: WO2008047989A1] The present invention discloses a metal separator for a fuel cell including a reaction gas channel formed to protrude from a first face of the metal separator to a second face thereof, a coolant channel formed between the reaction gas channels protruding from the second face of the metal separator, a reaction gas manifold opened to introduce a reaction gas into the metal separator, a coolant manifold opened to introduce a coolant into the metal separator, and a stepped portion positioned at any one of the space between the reaction gas channel and the reaction gas manifold, and the reaction gas channel. This configuration serves to widen the reaction gas flowing portion and the coolant flowing portion on the metal separator, and prevent deformation of the reaction gas flowing portion and the coolant flowing portion, thereby improving efficiency of the fuel cell.
